could you help me solve these problems? Here they are in English, if you can add a brief explanation I would greatly appreciate it.
1. Cylinder C has a mass of 10 𝑘𝑔 and is attached to the end of a rod whose mass can be neglected. If the structure is subjected to a couple 𝑀=(8𝑡2+5) 𝑁∙𝑚, where 𝑡 is in seconds, and the cylinder is subjected to a force of 60 𝑁, which is always directed as shown, determine the velocity of the cylinder when 𝑡=2 𝑠. The cylinder has a speed 𝑣0=2 𝑚/𝑠 when 𝑡=0.
2. The four 5 𝑙𝑏 spheres are rigidly attached to the crosshead of negligible weight. If a couple moment 𝑀=(0.5𝑡+0.8) 𝑙𝑏∙𝑝𝑖𝑒 is applied, where 𝑡 is in seconds, as shown, determine the speed of each of the spheres in 4 seconds from rest. Ignore the size of the spheres.
